A gunman killed and injured protesters at a BLM march. Why did police blame the victims?

Survivors of a mass shooting have publicly shared video contradicting police claims that victims were armed and part of a confrontation'

Two years after an attacker shot five volunteers before a Black Lives Matter march in Portland, Oregon, killing a 60-year-old woman and leaving one of her young friends paralyzed, a new visual investigation of the attack reveals that the assailant tried to provoke a stand-your-ground situation, daring three women to fight him, before suddenly opening fire when they refused.

Research agency Forensic Architecture collaborated with survivors on a reconstruction of the attack, analyzing helmet-camera video recorded by one of the victims, police radio traffic obtained through public records requests, and the testimony of 11 witnesses - including the volunteer armed guard who stopped the rampage by shooting and disarming the gunman.
